TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987 A truncated conical rotor undergoes unstable vibration when it is partially immersed in water and driven at a supercritical speed. The unstable vibration is a forward whirl and occurs at a limited range of rotation speed and rotor immersion in water.

Universal Strategy for Phase‐Selective Synthesis of Monolayer TMDs via Colloidal Chemistry
Advanced Materials, EarlyView.ABSTRACT Colloidal synthesis of monolayer transition metal dichalcogenides (TMDs) remains challenging regarding uniform size, thickness, and crystalline phase. While significant progress has been made in phase engineering, a unified chemical strategy for on‐demand selection of both 2H and 1T′ phases across multiple TMD systems within a single chemical ...
